Warehouse Slab-on-Grade Concrete Condition Survey and Design Review

Location: McAllen, Texas

The 14,000 sq. ft. warehouse facility consisted of a cast-in-place reinforced concrete slab-on-grade with perimeter and interior concrete grade beams and CMU exterior and interior walls. CA was retained to determine the cause(s) of the distress which was observed within weeks of the placement of the concrete slab-on-grade. Distress included concrete cracking, surface delamination, dusting of the concrete slab, cracking of the floor tile in the office spaces, and cracking of the CMU walls. CA’s investigation included, among others, a comprehensive condition survey including concrete coring non-destructive testing to locate reinforcement, petrographic examination, review and evaluation of the engineering design and project specifications, plans and drawings, construction procedures, and concrete materials and their proportions. In addition, CA performed a detailed review and analysis of the concrete production records and concrete placement procedures and also aided in litigation support for this project.
